VINS-Mono: A Robust and Versatile Monocular Visual-Inertial State Estimator

11 code implementations13 Aug 2017 Tong Qin, Peiliang Li, Shaojie Shen

A monocular visual-inertial system (VINS), consisting of a camera and a low-cost inertial measurement unit (IMU), forms the minimum sensor suite for metric six degrees-of-freedom (DOF) state estimation.

Trajectory Prediction with Graph-based Dual-scale Context Fusion

1 code implementation2 Nov 2021 Lu Zhang, Peiliang Li, Jing Chen, Shaojie Shen

In this paper, we present a graph-based trajectory prediction network named the Dual Scale Predictor (DSP), which encodes both the static and dynamical driving context in a hierarchical manner.

MonoJSG: Joint Semantic and Geometric Cost Volume for Monocular 3D Object Detection

1 code implementation CVPR 2022 Qing Lian, Peiliang Li, Xiaozhi Chen

Based on the object depth, the dense coordinates patch together with the corresponding object features is reprojected to the image space to build a cost volume in a joint semantic and geometric error manner.

Joint Spatial-Temporal Optimization for Stereo 3D Object Tracking

no code implementations CVPR 2020 Peiliang Li, Jieqi Shi, Shaojie Shen

Directly learning multiple 3D objects motion from sequential images is difficult, while the geometric bundle adjustment lacks the ability to localize the invisible object centroid.

Temporal Point Cloud Completion with Pose Disturbance

no code implementations7 Feb 2022 Jieqi Shi, Lingyun Xu, Peiliang Li, Xiaozhi Chen, Shaojie Shen

With the help of gated recovery units(GRU) and attention mechanisms as temporal units, we propose a point cloud completion framework that accepts a sequence of unaligned and sparse inputs, and outputs consistent and aligned point clouds.

You Only Label Once: 3D Box Adaptation from Point Cloud to Image via Semi-Supervised Learning

no code implementations17 Nov 2022 Jieqi Shi, Peiliang Li, Xiaozhi Chen, Shaojie Shen

The image-based 3D object detection task expects that the predicted 3D bounding box has a ``tightness'' projection (also referred to as cuboid), which fits the object contour well on the image while still keeping the geometric attribute on the 3D space, e. g., physical dimension, pairwise orthogonal, etc.

Are All Point Clouds Suitable for Completion? Weakly Supervised Quality Evaluation Network for Point Cloud Completion

no code implementations3 Mar 2023 Jieqi Shi, Peiliang Li, Xiaozhi Chen, Shaojie Shen

In this paper, we propose a quality evaluation network to score the point clouds and help judge the quality of the point cloud before applying the completion model.
